Abstract (en)
[origin: EP0763748A2] Magnetoresistive elements according to this invention comprise magnetically soft material (33) in close proximity to the magnetoresistive material (32), exemplarily a perovskite manganite. The combination results in magnetic field "amplification", with large resistance changes attainable at relatively low applied fields. The invention exemplarily is embodied in magnetic sensors, e.g., magnetoresistive read/write heads (30). <IMAGE>
